Niels Martin Hansen 49acbaa6e5 Fixed Automation script loading error messages (bug #1)
Fixed karaoke timing not being committed correctly (bug #7)
Changed some throw _T() into throw wxString()

Several architectural changes to Automation karaskel family.
Automation karaskel has Furigana, Inline-fx and Out-of-line-fx support added (still needs tweaking and bugfixing)

Originally committed to SVN as r131.
